The Big Sky Wheelchair Rifle Rest is designed for those who want to hunt/shoot but may lack the arm or hand strength or the stability to do so. It's available in two versions. Paraplegic: Set up consists of: (1) putting aluminum base-sheet on wheelchair seat (threaded hole facing front); (2) placing seat cushion on top of base-sheet then sitting down; (3) screwing plastic boss into threaded hole; and (4) inserting rifle rest into plastic boss. The fore-end support half-round is designed to rotate 360º, pivot up and down under spring pressure, and turn side to side, providing height adjustment and directional flexibility. Semi-quadriplegic: Same as the paraplegic version with addition of an attachment for the back of the rest that holds the rifle on the rest by itself.
